First evidence of tumor-like anomaly infestation in Copepods from the central Indian Ridge
(NISCAIR, CSIR, 2008)To investigate the distribution and abundance of mesozooplankton in the Indian Ocean, zooplankton sampling was conducted along the Central Indian Ridge (CIR) from the equatorial waters to 8 degrees S latitude. Of the seven ... -
Enhancement of vertebrate cardiogenesis by a lectin from perivitelline fluid of horseshoe crab embryo
(Birkhäuser Basel, 2008)Cardiac myocytes are the first cells to differentiate during the development of a vertebrate embryo. A wide variety of molecules take part in various steps in this process. While exploring biologically active molecules ... -
Recently studied sedimentary records from the eastern Arabian Sea: Implications to Holocene monsoonal variability
(The Society of Earth Scientists, 2008)Deep insight into exact mechanism(s) controlling past monsoonal variability on inter-annual to millennial time scales is a pre-requisite for developing predictive capability of monsoon on timescales relevant to human life. ... -
Warm pool thermodynamics from the Arabian Sea Monsoon Experiment (ARMEX)
(American Geophysical Union, 2008)Before the onset of the south Asian summer monsoon, sea surface temperature (SST) of the north Indian Ocean warms to 30-32 degrees C. Climatological mean mixed layer depth in spring (March-May) is 10-20 m, and net surface ... -
A microdiversity study of anammox bacteria reveals a novel Candidatus Scalindua phylotype in marine oxygen minimum zones
(Society for Applied Microbiology, 2008)The anaerobic oxidation of ammonium (anammox) contributes significantly to the global loss of fixed nitrogen and is carried out by a deep branching monophyletic group of bacteria within the phylum Planctomycetes. Various ... -
Intramolecular Wittig reaction: A new synthesis of (S)- pyrrolam A
(Verlag Helvetica Chimica Acta AG, 2008)A straightforward synthesis of (S)-pyrrolam A is described. The synthesis involves in situ generation of the phosphorane 3, followed by an intramolecular Wittig reaction to furnish (S)-pyrrolam A -
The next generation of iron fertilization experiments in the Southern Ocean
(The Royal Society, 2008)Of the various macro-engineering schemes proposed to mitigate global warming, ocean iron fertilization (OIF) is one that could be started at short notice on relevant scales. It is based on the reasoning that adding trace ... -
Molecular diversity of RelA enzyme in marine bacteria- A bioinformatics analysis
(MD Publications, 2008)The RelA (relaxed) protein is a crucial protein related to unculturability in bacteria. In response to nutrient scarcity, most of the marine bacteria are known to enter a viable but non-culturable (VBNC) state, but remain ... -
Effect of hydrodynamic cavitation on zooplankton: A tool for disinfection
(Elsevier, 2008)Application of hydrodynamic cavitation for disinfection of water is gaining momentum, as it provides environmentally and economically sound options. In this effort, the effect of cavitating conditions created by differential ... -
Biogeochemistry of the surficial sediments of the western and eastern continental shelves of India
(Coastal Education and Reserch Foundation, 2008)Even though continental margins cover only about 7-9 % of the world ocean area, they are important sites for organic carbon accumulation and hence play a major role in biogeochemical carbon cycling. Surface sediments from ... -
Antibacterial activity of synthesized 2,4,5-trisubstituted imidazole derivatives
(Blackwell Munksgaard, 2008)Some novel chemically synthesized 2,4,5-trisubstituted imidazoles from aryl aldehydes and 1,2-diketones or a-hydroxyketone were screened against eight different human pathogenic bacteria and fungi. Seven compounds were ... -
Temporal variation of diatom benthic propagules in a monsoon-influenced tropical estuary
(Elsevier, 2008)Temporal variations in the diatom benthic propagule (DBP) community and their role in the phytoplankton community in a monsoon-affected tropical estuary, Zuari estuary, Goa (India) are presented. The DBP from the sediments ... -
Laccase treatment of recycled blue dyed paper: Physical properties and fiber charge
(Society for Industrial Microbiology, 2008)Recycled blue colored paper was treated with laccase under various combinations of physical and chemical parameters including enzyme concentration, temperature, oxygen, and reaction time. Laccase treatment of recycled dyed ... -
Sources of hydrocarbons in sediments of the Mandovi estuary and the Marmugoa harbour, west coast of India
(Elsevier, 2008)Surface sediments were collected from various locations of the Mandovi estuary and the Marmugoa harbour, Goa, India. Sediments were analysed for organic carbon (OC), total lipids, n-alkanes concentration and composition. ... -
Evaluation of impairment of DNA integrity in marine gastropods (Cronia contracta) as a biomarker of genotoxic contaminants in coastal water around Goa, west coast of India
(Elsevier, 2008)The measurement of the impairment of DNA in marine gastropod (Cronia contracta) provides an insight into the genotoxic effects of contaminants on marine organisms along the Goa coast. The impact of genotoxic contaminants ... -
Elemental oxides analysis of the medieval period glazed ware from Gogha, Gulf of Khambhat, Gujarat, India
(Current Science Association, 2008)During an inter-tidal zone exploration in the Gulf of Khambhat region, a large number of glazed and nonglazed sherds were recovered along with stone anchors dating back to the late medieval period. Four representative ... -
Formation of algal bloom in the northern Arabian Sea deep waters during January-March: A study using pooled in situ and satellite data
(Taylor & Francis, 2008)The formation of winter bloom (January-March) was studied in deep waters of the northeastern Arabian Sea (NAS) during 2003 and 2004. Six ship cruises were undertaken at different phases of the bloom to examine its formation. ... -
Hyperspectral radiometric observation of the northeast Arabians Sea during April 2006
(The Indian Society of Remote Sensing, 2008)Parameters were retrieved from the hyperspectral radiometer like upwelling and downwelling radiance (Lu and Ed) upwelling and downwelling attenuation (K-Lu and K-Ed) for 9 stations in the northeast Arabian Sea between 16-26 ... -
